Application filed January 28, 1925. Serial No. 5.243.

This invention relates to railway cars and particularly railway passenger cars oi.z the articulated type in which each car unit comprises a plurality of car bodies. the adjacent ends ot tivo ot 'vvliich arc carried vby a single truck and has for an object the provision ot side supports or bearings between the truck andA the adjacent ends of two oi the bodies of a car unit.

Another object ot the invention is to 'provide the adjacent ends of tivo ot the bodies ot an articulated car unit Witha side bearing.` 'which is automatically adjustable to the ear truck` and to the car bodies at all times.

Another object of the invention is to provide. the adjacent ends of two ot the bodies ot' an articulated car unit with roller side bearings which are adapted to engage aside bearing mounted on au adjacent car truck.

These and other objects will he apparent from the following description.l Referring to the drawings in which like reference characters refer to like parts, Fig'. 1 is a plan vieiv ot portions of the adjacent ends ot tivo car bodies of the articulated car unit; Fig. 2 is an enlarged longitudinal sectional view' ot the saine taken on the line 2-2 ot' Fig. 1` and Fig. il is a cross sectional vie-vv ot the same. taken on the line ,3v-3 of Fig, Q. i

Referring now in detail to the drawings the reference character 1 indicates an arvv ticulated car unit which comprises a plurality ot' car bodies 2. the adjacent end portions 'ot tivo of which have been shown in the drawings. rll"hcse`ends 3 are provided with bod)7 renter plates Ll., both ot' which engage a truck center plate 5 mounted on a truck bolster 6, which bolster 'is a part of' the truck '7. These center plates l and 5 are so' termed ends thereof` are overlapped by the adjacent preferably circular' for a portion 'ot' its length. and preferably square for the rcmainder o't its length. 'lhe louer Aportion of the member 11 is provu'led .'vitli spaced lugs 13, between and iu which a roller 14: is ro-` tatably mounted` such roller being adapted to engage with the upper surface 9 of the truck side bearing?.w 8. llbove the roller la this member is provided with a spring seat 15, on which the lower end oi a spring` 1G seats, the upper end ot such spring; seat ingr en the inner surface of the top wall 17 of the recess 12. The spring seat 15 is preferably .square in form and tits loosely inthe square portion of the recess 12 and will permit tree vertical movement between the side beariugand the underframe, but will prevent any undue rotation of 'the side bearingl relative to the underframe. This member is also provided rwith a projection 18. which extends upwardly from the spring seat 15. through the spi'ingi` 16 and through the wall 17. which torins the top of the recess 12, and adjacent the upper end thereof is provided with a nut 19 and 'Washer 90.

To prevent the Washer yfrom chattering a" spring 21 is provided which surrounds the projection 18 and at its lower end seats on the vvall il? and at its upper end seats on the under sident the Washer 20. lt will be noted that the body side bearings are movable vertically relative to the underframe and lthat the springs mounted in the under traine and seated on the member 11. render the side bearings automatically adjustable, thus insurine a proper bearing between the car body and` the truck at all times and under all servieeonditions. f lt will be apparent to those skilled in the art to which this invention appertains that changes may be made in the details of the several parts forming the invention Without departiner from the spirit and scope of the appended claims.
